  • 1.  messagelabs.com Connection timed out

    Posted Jul 03, 2017 08:18 PM

    Hello

    We're experiencing problems when sending to email addresses that use messagelabs.com MX. See below;

    cluster4a.us.messagelabs.com[216.82.251.230]:25: Connection timed out

    I tried to connect by telnet...

    accept-deny-server.PNG

    This is happening for various accounts on our server which is sending from IP Address 52.187.61.132

    I have used this;

    http://ipremoval.sms.symantec.com/lookup/

    to check on our IP and it tells there is no problem with the IP Address.

    The IP address you submitted, 52.187.61.132, does not have a negative reputation and therefore cannot be submitted for investigation.

    Can you please help us resolve this issue as it's causing me headaches!

    Thanks

    Hi

    It appears that our service was throttling this IP as we've likely seen spam coning from this IP in the past. I've now cleared the throttling on the IP so you should not see any issues with this going forwards,

    Can I ask you to check and confirm and then if everything is working as expected can I ask you to mark this thread as resolved.

    Thank you
